BUILDING SECTION.

Application filed June 3, 1921. Serial No. 474,733.

To all whom it may concern:

Be it known that we, ALEXANDER C. BROWN and HARRY GILLETT, citizens of the United States, residing at Cleveland, in the county of Cuyahoga and State of Ohio, have invented a new and useful Improvement in Building Sections, of which the following is a'full, clear, and exact description, reference being had to the drawings accompanying and a part of the specification, wherein similar parts are designated by similar numerals in each case.

Our invention relates more particularly to that class of constructions, like roofs,

w walls, and flooring, which require as a main component or element, a preformed building section, that combines, in marked proportions, the qualities of rigidity, strength, and insulation, with a minimum of weight,

mass, and placement operations. It is the purpose and object of the present invention therefore to provide a special preparation or composite, of the nature abovereferred to that will meet all requirements, and in an to exceptional degree.

We accomplish this object by a' unitary article, which, broadly speaking, consists of a body ortion of cork mastic compressed and mol ed into a slab like section, around 80 a central reinforcing form or sheeting which,

except as specially explained herein, is substantially equidimensional with. said body portion itself and the component half portions that characterize the same.

In the accompanying drawings, Figure 1, is a plan view of a slab or board, representing said invention, the dotted lines in the same indicating the side edges of the centrally placed reinforcing material. Figure 2 40 is an enlarged View of a, portion of the end of the slab. Figure 3 is a vertical sectional view on the lines 88 of Figure 1; Figure 4 is a developed view of a slab such as appears in Figure 2, when the reinforcing ma- 46 terial perforated; Figure 5 is a special form of a section when the reinforcing material is of a kind and is exposed in a mannor to permit of the ends and sides interlocking with similar exposed portions of contiguous sections. Figure 6 is an enlarged broken View of the end of the board shown in Figure 5, and Figure 7, a perspective view of a plurality of the boards in a roof, or other formation.

$5 The reinforcing element may be of any suitable material or form, such as plate, wire-mesh, expanded or corrugated metal, or latticed wood, that has a, positive or plus quality of rigidity and strength. The various kinds of corrugated metal will be pre ferred for the purpose, and, of these, the socalled ferroinclave form of sheet metal, as set forth in United States Letters Patent 689281, showing corrugations with claviform or dovetailed cross-sections, has distinct advantages in this and. other respects in the connection, and is made the basis of a special claim accordingly.

Where plate, or forms of metal other than dovetailed are used for said element, special 70 provision should be made for securing the mastic element in place around the same, either by connecting the mastic portions of said element directly to the faces of the reinforcing element with which they are in contact, or to' each other.

A provision for the latter alternative, is illustrated in Figures 2 and 4. It is applicable when plate is used, or material having corrugations with other than dovetailed H cross-sections.

l/Vhatever form of reinforcing element is selected, it will substantially conform, in superficial dimensions, or shapeto the predetermined form of the finished section, and, in the process of compressing and molding the cork-mastic about the same, said element is to be so arranged and handled that, in the final result, it will be centrally related to said section. This requirement will be readily understood by those practiced in the art,

and need not be further set forth here, as is likewise the case with respect to the various sta es and requirements of the process itsel As to the latter operation, it is expected, of course, that the union of the cork member around the reinforcing member, in order to form said section, will be brought about by the firm compression of the same into molds containing said reinforcing member in such manner and under such physical and other conditions that said mastic will be forced into the dovetailed corrugations when ferroinclave is used, or through, or into said perforations or other connection provision, where other material is used for'the reinforcin member, in order to thereby lastingly 0nd and compact said elements together.

In said drawings, A, Fig. 1, is a full view 110 of a primary form of the completed article and section. In such form the planeportions of the cork envelope 15, around the.

reinforcing central member of said article, are equidimensional, one with the other, and substantially with the member they enclose. The dotted lines in said figure indicate the side edges of said embedded member.

In Figs. 5 and 6, as a special'form of the invention, the coveringlayers of cork, 16 and 17, corresponding? with the plane portions, or layers 15 in ig. 1, are not in contact with each other at all, but are made to occupy oppositely related and smaller areas on the reinforcing member than as shown in Fig. -1. This form may be produced from the sectional form shown in Fig. l by removing equidimensional rectangular strips of the cork covering 15, from and along alternate ends and sides of the two faces,

to such an extent as will expose oppositely related portions of the central reinforcing medium, and adapt the same to be brought into bearing with correspondingly exposed parts of similar sections.

In Figures 5, 6 and7, for instance, as will be seen, by reason of making the mastic layers rectangular and smaller than the central sheet or member 14: in the manner described, they'will be located at opposite corners or angles of the faces of said member, with two adjacent edges coincident with two adjacent and opposite edges of the member in each case, and the latter, because of its larger area or size, will extendbeyond, the layers, and be exposed as strip-like por-- tions 16* and 16", along the top and right hand side of the u per face of the member, and 17 and 17, a ong the bottom and left hand side of the other or under face,while the layers themselves, will severally cover the remaining portions of the sheet member in opposite and reversed relations to the same and to each other; It accordingly 'follows that the exposed strip-like portions 16 and 16", andl'? and 17", and the edges of the layers adjacent thereto, in a finished section, will always compose orform a recess or rabbet a-lon the sides and edges of the section, that 1 1 usefull interlock and engage with the correspon ing recesses in similar sections, when such are brought together in a given construction for the purpose. The width of the strip-like portions referred to, will, of course, do end upon the requirements of each case, Fig. 2.)

The edges of the layers along said lines should he squared and be even with the edges of the sheet, and, when a ferroinclave sheet is used as 14, in Fi 6, it will be obvious that the sheet shou d be so calculated as toterminate at the sides with the horizontal member of a corrugation.

When said section A, or said modified form thereof, B, ismade up as described,

the resulting product will present a building material that is ready for shipment in a form for immediate use at the site of erection, whereby the delay, loss and cost of separate handlings of the essential components of the same, are avoided or 'largely reduced. In the secondary form of the invention (see Figs-5 and 6), by reason of the union of the particular constituents in the special manner illustrated, all the .advantages of scarfed and overlapping joints, in assembling the sections in a given structure, are obtained without the coeflicient of weakness that characterizes structural unions of that kind, where the material parts,involved must'first be reduced in order to fit together in a level joint.

Although cork and cork mastic are used in the foregoing description, it is to be understoodthatwe do not intend to limit cork mastic so located on and with respect a to one face of said member that two adjacent edges of the same coincide with two adjacent edges of the stifiening member, a rectangular 1 layer of cork mastic of thesame size as the spect to the other face of said member that corresponding edges of the same coincide with two other adjacent edges of the stifiening member, said layers being of equal dimensions one with theother, and of such size with respect to said faces, that, when in their described places thereon, the exposed faces and the edges of the layers adjoining the same, will together form rabbeted recesses for interlocking engagements with corresponding recesses in similar building sections whenbrought together for the purpose.

2. As an article of manufacture, the combination of a corrugated-rectangular sheet member, a smaller rectangular layer of cork mastic on one face thereof so located with re,- spect to such face that two adjacent edges of the same coincide with two adjacent edges of the sheet member, a rectangular layer of cork mastic of the same size as the first named layer on the otherface thereof, so locatedlwith respect to such face, that corresponding edges of such layer coincide with the two adjacent edges ofsaid member opposite to the first named adjacent edges first named layer, so located on and with relid thereof, the superficial dimensions of said its the superficial dimensions of said member, that, when in their described places relative to each other, the exposed faces of said member and the edges of the layersv severally adjoining the same, will together form rabbeted recesses in the section for interlocking engagements with corresponding recesses in similar building sections when brought together for the purpose.

3. A preformed building section, comprising the combination of a rectangular ferroinclave stiffening member, a rectangular layer of cork mastic of lesser superficial dimensions than said member in firm contact with one face thereof, with two adjacent edges of the layer coincident with two adjacent edges of the member, a rectangular layer of cork mastic, of the same dimensions as the first named layer, in similar contact with the other face of said member, with corresponding edges of the same coincident with the two adjacent edges of said member opposite to the first named adjacent edges thereof, the size of said layers being so proportioned with respect to the size of said member, that, when in their described places relative to each other, the exposed faces of the member and the edges of the layer severally adjoining the same, will together form rabbeted recesses in the section suitable for interlocking engagements with corresponding recesses in similar building sections when brought together for the purpose.

4. As an article of manufacture, a preformed building section, comprising the combination, with'a rectangular strengthening member, of a rectangular layer of cork mastic of smaller superficial dimensions on one side of the same with two adjacent edges coincidental with two'adjacent edges of the member, a rectangular layer of cork mastic equidimensional with the first named layer, on the other side of the member with its corresponding edges coincidental with two adjacent edges of said member opposite to the first named edges of the member,- the size of said layers bein so proportioned with respect to the size of said member, that when in their described places relative to each other, the exposed faces of the member and the edges of the layers severally adjoining the same, will together constitute rabbeted recesses in the section suitable for interlocking engagements with corresponding recesses in similar building sections when brought together for the purpose, substantially as shown and described.
